In this video Michaela Clowser, Tammy Vaassen and Bill Halfman discuss the 2022 NCBA Quality audit results with dairy and beef producers.
In this UW-Madison Extension Dairy Program webinar, Department of Animal & Dairy Sciences Lactation Physiology Professor Laura Hernandez discusses calcium metabolism in the mammary gland, the physiology during the transition period, and other things the mammary gland needs to thrive.
Handling cows is necessary to harvest milk and provide animal care, but these interactions also present a risk of injury to personnel. Inappropriate cow handling threatens animal welfare, milk production, and public trust in dairy farming. But how can the industry best teach these skills? Interactive learning experiences can help build confidence by allowing dairy workers to actively participate in their own training.
When it comes to health issues on a dairy farm, lameness is usually a main concern along with mastitis and reproductive issues. Lameness includes any abnormality which causes a cow to change the way she walks.
The sheer volume of information collected on a dairy farm may seem daunting to keep track of, but proper recordkeeping can play a vital role when making decisions. One area that may not receive as much attention is animal health events, especially hoof health. How would your current animal health records rate if they were compared to the requirements established by the Food and Drug Administration (FDA) Code of Federal Regulations (CFR) 21CFR530.5?
Nutrition affects more than just the cow’s digestive system. The effects of an imbalanced diet can be seen throughout the animal’s body. Of particular interest are concentrates, such as grain-based feed ingredients, that typically contain high amounts of sugar and starch.
Dairy cow housing facilities are a double-edged sword regarding hoof health and lameness. Built right and managed properly, housing facilities can limit the problem and aid recovery.
Hoof health is essential for not only the overall health of the animal, but also for her welfare. Digital dermatitis (DD), or hairy heel warts, is an extremely painful condition for dairy cattle, reducing their ability to walk to and from the milking parlor, or to the feed bunk. Based on USDA NAHMS 2017 data, 16.8% of all cows and 2.6% of bred heifers have lameness on a dairy operation.
Raising calves is a huge expense on any dairy farm and getting them off to a great start is important in cold weather as much as warm weather. Cold stress can increase the risk of disease in pre-weaned calves.
Even though hypocalcemia, commonly known as milk fever, has been a fresh cow problem for years, it has been addressed through nutritional management during the dry period and early lactation to decrease clinical cases to less than 1%. However, 73% of 3rd and greater lactation animals have had subclinical hypocalcemia.
